气缸是一种利用压缩空气实现运动的元件，因此顾名思义，被称之为“气缸”。 气缸适用于众多应用领域，甚至可以在极端恶劣的环境条件下稳定工作，是一种极具成本效益的解决方案。其调试过程也极为简便，优势更为突出。 气缸的速度可达 10 mm/s 至 3 m/s。 由于空气具有可压缩性，这让气缸不仅坚固耐用、使用灵活，还能承受较大的外部作用力。
气缸在自动化技术/工厂自动化领域有着广泛的应用。 气缸的典型应用领域包括夹紧、升降、沉孔、推、拉、送料、旋转、抓取、夹持与保持、接合、挡停、冲压以及压印等。
Festo 的气缸产品范围包括活塞杆气缸和无杆气缸（直线气缸）、摆动气缸、串联气缸、多位置气缸和止动气缸，以及夹紧气缸、带直线导导向的气缸和气囊式及膜片式气缸。 我们的产品系列包含多款标准气缸，其尺寸和安装接口均采用标准化设计。 所有气缸遵循同一标准，尺寸完全相同。 无论圆形活塞杆气缸 (ISO 6432)、紧凑型活塞杆气缸 (ISO 21287) 以及型材和拉杆气缸 (ISO 15552)，它们均有相应的标准规范。
Festo 活塞杆气缸是一种用于执行直线运动的气动执行器。 作用在活塞上的能量通过活塞杆传递给待移动的部件。 活塞杆气缸的类型包括圆形气缸、型材气缸、紧凑型气缸、短行程气缸、扁平气缸、微型气缸、插装式气缸及不锈钢气缸。
无杆气缸，顾名思义，是一种没有活塞杆的气缸。 虽然无杆气缸没有活塞杆，但也能执行直线运动，因此也被称为直线驱动器。 无杆气缸主要应用于行程较长的场合，例如作为多轴门架的基本驱动器，或用于送料任务。
Festo 的摆动气缸可实现带动运动，摆动角度最大可达 270°。 叶片式摆动气缸和齿轮齿条式摆动气缸通常均具备高精度特性，在性能表现和适用灵活性方面也极为出色。 因此，我们的气缸被广泛应用于众多行业领域的工厂自动化。
串联气缸由两个相同的型材缸筒气缸串联连接而成，可使两个运动方向的推力均增加一倍。 倍力气缸是一种由多个气动紧凑型气缸串联连接而成的气缸。 多位置气缸分为两种规格：一种配备两个独立气缸，另一种则配备两个至五个串联气缸。
Festo 导向杆气缸是配备导向杆及直线导轨的气动驱动器，属于工业自动化领域中的核心执行部件。 这类气缸广泛应用于各种场合，例如升降、压装、牵引、推送、夹紧、止挡、保持、切割、分离等。 两种导向杆气缸均兼具直线运动与导向运动的优势，并以其极高的稳定性而著称。
Festo 输送隔离器广受欢迎，是一款非常可靠的输送技术解决方案。 输送隔离器可简化工件供料过程，适用于需要对连续工件流进行分离并逐一送至下游设备的场合。 止动气缸是一种用于在运输系统中阻挡工件支架或机器部件运动的气缸，可带缓冲或不带缓冲。 带缓冲功能的止动气缸可在运输系统中阻挡高达约 800 kg 的负载。
夹紧气缸直接利用气动夹紧元件或通过运动机构，对工件执行保持或夹紧操作。 在非工作状态下，夹紧元件会从作业区域退出。 得益于其运动学特性，夹紧气缸能够以较低的能量输入实现非常高的夹持力。
Pneumatic rotary indexing tables can be used to carry out continuous rotary movements. Rotary indexing tables are used, for example, in assembly applications. A variable direction of rotation and freely selectable indexing enable a wide range of applications.
Shock absorbers absorb the energy of a moving drive. The movement of the drive piston is brought to a standstill by rubber elements and/or hydraulically. The relatively gentle stopping before the end position prevents a strong impact as well as a spring-back; it also protects the drive and the machine parts from wear or irreparable damage.
The attachments and accessories for pneumatic cylinders offered by Festo include mounting elements for drives and sensors, piston rod attachments, linear guides, accessories for direct valve mounting, clamping elements, freewheel units, accessories for cushioning elements and drive-specific accessories.
In a pneumatic cylinder, the compressed air is used to exert force on a cylinder piston in order move it in a specific direction. The movement of the piston is transferred to the parts to be moved by a piston rod or a frictional connection. A pneumatic cylinder is a drive operated with compressed air usually up to a maximum of 12 bar in order to generate linear or rotary motion. A distinction should be made between single-acting and double-acting cylinders (work is performed only in one direction or in both directions).
A single-acting pneumatic cylinder only has one compressed air connection. The incoming compressed air moves the piston in one direction, and the cylinder force is built up in this direction. If the piston needs to return to its initial position, the air is simply expelled from the cylinder. The mechanical spring pushes the piston back to its initial position. This part has a ventilation/exhaust hole so that no excess or low pressure is generated through the piston movement in the second cylinder chamber.
Benefits:
Disadvantages:
The double-acting cylinder requires compressed air for every direction of movement. On this type of cylinder, the force in both the advancing and retracting direction is built up using compressed air. The simplest way of actuating a double-acting cylinder is by using a 5/2-way valve.
Benefits:
Disadvantages:
Get the basics right first. Use our design and selection tools to size your cylinder for the speed and force you need, while keeping air consumption under control.
Then fine-tune motion on site. Add flow/speed control valves (throttles) as a cylinder speed controller to stabilize extend and retract speeds without redesigning the mechanics.
Optional: configure the full setup in 3D. Build your assembly in our 3D design tool, including mounting parts, sensors and all accessories.

Finally, keep performance predictable with AI support. Monitor cylinder behavior for maintenance and quality using Festo AX (AI-based standard apps) to detect deviations early and support planned intervention.
